The I-pipe and Cobalt ports to x86_32 received neither careful
maintenance nor testing for ages. In addition, Dovetail does not support
the 32bit legacy mode, and there is no plan to do so. Therefore I
recommend to stop supporting the x86_32 architecture starting from
Xenomai 3.2, which echoes what Jan has been saying for quite a while
about this issue too.
If you do care about running Xenomai on this architecture and are
willing to maintain such a port in the long run, this is definitely the
right time to make your case, asap.
Thanks,

Agree, plenty of Linux distro dropped x86_32 years ago.

Just to clarify: This affects the host kernel, not 32-bit userland
(compat), right? The latter is still a must-have in several applications
here, and I think beyond as well.
BTW, we should also deprecate the x32 ABI.

Only 32bit kernel support would be dropped, 32bit compat over 64bit
would stay.

Agreed.
