I simply wanted SIGINFO and VSTATUS, and that necessitated this. If
the limit of 1024 rt signals is an issue, that's an extremely simple
change to make.

This patch set expands the number of signals in Linux beyond the

this cap. This limit is not fixed and can be further expanded within
reason.
Could you explain the point of the entire exercise? Why do we need more
rt signals in the first place?
glibc has quite a bit of utterly pointless future-proofing. So "they
allow more" is not a good reason - not without a plausible use-case,
at least.
