Thanks, in that case I think this is a known issue, and we decided not
to fix it on the emacs-30 release branch because building the pretest
tarball (which doesn't require to go via bootstrap) works with the
original pure-size.

Andrea, what did we decide regarding the long-term solution for this?
Did we mean to somehow solve the issue with dynamic doc strings?
