Why should it break? Docker supports versioning (tagging). So you could have a
tag latest point to the latest TeX Live but provide tags for older releases.
Have a look at the images of the Island of TeX:
They provide latest and historical releases.

When using tagging the user could fetch a versioned (read TL year) image.
Because the ISO images of old releases do not change there would be no broken

What's missing from the ISO images that are provided on the mirrors? They are a
complete snapshot of the software at that time.
