While this is more software design philosophy than vim-specific, it's
because every configurable behavior requires code to parse the new
option (however minimal), code to use the new option, one or more tests,
documentation changes, it makes the code that little bit harder to
maintain and learn, and it makes learning to use the software a little
bit harder. If the new behavior is significantly better, then yes, why
not. I'm not sure if this qualifies.

There's a difference between changing long-existing behavior and adding
new behavior. Yes, I wouldn't be happy if bs=2 went away, I use that all
the time (with BS). But that's not what we're discussing here (a fairer
comparison would be if it was changed so BS would have to be hit a
second time upon hitting the start of inserted text to continue into
existing text. While changing it now would affect decades (literally!)
of muscle memory, in time I'd learn, and if it had always worked that
way, I would have seen it as a feature.)

Anyways, as I said, this is completely up to Bram (and Christian). I'm
certainly not going to like and use vim any less if the new option and
behavior is added (or if it's not), just offering my opinion. I'm nobody
:-), so feel free to ignore it.
