Yes, that makes sense to me.

This would effectively be two competing RFCs and that could work with 
our voting policy. One possible issue is that folks might be biased 
against voting for the upgrade if there is the INI escape hatch. I 
really don't like the extra maintenance effort (e.g. duplicate code 
paths that no one is going to test) of the INI. I generally think an 
opinionated RFC by a subject matter expert (i.e. you :-)) is stronger 
than one that leaves every decision up to the voters.

IMO it should be a vote for the increased minimum version with a good 
argument as to why this increased minimum version is useful, 
specifically “more predictable behavior for persistent connections, 
because any per-connection state can cleanly be reset” and “support for 
C11 in autotools, which already is the documented minimum in 
https://github.com/php/php-src/blob/8d0777e88b8494807727fc57c148c2497976eff5/CODING_STANDARDS.md?plain=1#L12, 
but folks will only notice if compilation fails halfway through”.
