It did work for my rhel10 test. Not sure what went wrong in your case.

It did give the appearance of working in my case also (the unrecognised sieve directive errors went) but Sieve functioning did not work.

Did you try any Sieve processing on your RHEL 10 machine after the workaround?

Of course it (installing dovecot-managesieved as workaround not working) could well be down to my learning Dovecot/Sieve — this is my first Dovecot setup. My Rocky Linux 9 machine is fairly clean (new install, not moving to RHEL 10 yet) and I installed from packages from the repo with no problems.

Separate but related question - is there an uninstall option for Pigeonhole that was installed compiled from source? I still have the source directory on the machine.

In repo.dovecot.org, the libpigeonhole_settings.so went accidentically to dovecot-managesieved package instead of dovecot-sieve package.

The thing is though I installed dovecot-managesieved as you suggested and the error that Dovecot did not recognise any of the sieve directives in dovecot.conf went away **but there was still not any Sieve functionality**. I double/triple checked and confirmed that — only after installing Pigeonhole did Sieve work.

The pigeonhole compiled installation put more files into /usr/lib64/dovecot/settings/ than dovecot-managesieved did. This is my current listing after removing dovecot-managesieved and installing Pigeonhole from source. Installing dovecot-managesieved only put three files into Settings.

It did work for my rhel10 test. Not sure what went wrong in your case.
