I think it is worth some consideration sure, but there are removable/replaceable printing surfaces on the market which are affordable i.e. kapton. However there are things like Printbite, which though it might cost £20-£40 it works, and is permanent and extremely durable, I have a piece now in its 2nd year of printing.
I personally, since I use printbite for all three printers, with great satisfaction, see no merit in a replacement for kapton tape which is also a sheet of adhesive backed polymer that can be applied, printed on, and then replaced when it gets damaged which it will. It's not how cheap a surface is that matters, its does it provide good but not too much adhesion and how much hassle and time is involved in replacing it (and how often). This is why gluestick/painters tape/kapton/hairspray are IMHO all ridiculous - they are messy and time consuming, so no matter how well they work unless you only print one object a year the time involved in replacing them is worth on aggregate much more to you than the cost of a sheet of printbite.
Full disclosure - I have no financial interest in Printbite, I just rate it highly, and wish to support Mutley 3D who makes and sells it.

I'll test it when I find a suitable adhesive...
Since it is a plastic, it might be possible to use an electrostatic hold-down for it and eliminate the adhesive completely. I recently did an experiment with that for holding paper, but it should work fine for plastic, too. The electrostatic hold down is simple- I placed foil tape in an interdigitated finger pattern on one side of a piece of thin acrylic. I connected a HV DC supply to the two foil traces and paper stuck to the opposite side of the acrylic perfectly. For the next step I want to etch a single sided PCB. If you clamped such a hold-down on the print bed you could use it to hold the plastic film down while printing then release it when the print is finished. No scraping/prying. Just peel the plastic off the print and reuse or throw it away, depending on its condition when you remove it from the print.

@ECJ can you post a link to the type of transparency you are using?

I tried it, but the transparencies I had to hand were of unknown type and origin. The part stuck too well and I had difficulty getting it off, damaging the transparency in the process. I tried to get a box of transparencies from Staples but couldn't find any! Once I do track some down I'll give it another go. They are a lot thicker than the typical kapton tape, so I'm hopeful it will last longer. I need something for when I get the new printer going, and kapton, pei or printbrite would all be rather expensive for the roughly 650x300mm bed that I'm aiming for.

It did not arrive yet? Or were the tests a failure?

Have you considered 3M 468MP tape?
It works well to stick PEI to aluminium. It really sticks well. You can remove it, although it takes a scraper, half an hour, and lots of acetone.

Has anyone tried adhesive-backed polyester film from McMaster (https://www.mcmaster.com/#8689K42)?

In the description says it's PET. I already tested PET film and the result is not good. The adhesion of ABS to PET is worse than that of glass.
