Agreed. When I first noticed haproxy was not properly handling 1xx, I fixed
it and redeployed. The only thing (especially with intermediaries) is that
these components are rarely upgraded, so the ones facing bugs are replaced
and the ones without bugs stay in place for 5+ years. But the good thing is
that when something new breaks your old deployment, you quickly notice it,
realize you're running an outdated, unsupported version, upgrade to the next
one and notice it fixes your problem for free.

So yes, adding new 1xx status codes will definitely break existing bogus
code, and by the time their users notice, fixes will be available and the
issue will only last for the time it takes to update the package.
