OK. You did, however, spend an entire message on it.

Here's the thing: readonly is a rarely-used feature compared to most
others. There are not a lot of readonly variables, and I'm asserting
that script authors mark variables as readonly for a reason. It's
worthwhile to figure out why a variable is readonly and see if you're
circumventing the author's intent by shadowing it. In the case of
BASH_REMATCH, I explained why it is readonly.
