The KEYS file has historically been manually maintained.
As new keys are used for signing releases, they are added to the file.
However entries should not be deleted if they have ever been used to
sign a release, otherwise it may not be possible to check the sigs of
archived artifacts.

LDAP does not have all historic keys, or even all historic RMs.

So replacing the KEYS file with a copy from LDAP may lose keys needed
for validating archived files.

Directing users to the p.a.o/keys/groups/${project}.asc files should
work for current releases.
But even that has an problem - if the RM leaves a project whilst the
release is still current, the project.asc file will no longer contain
the RM's key

The problem is even worse for older releases.
People may create new keys and drop old ones which have been used for signing.
People leave a project or the ASF and the LDAP entry is changed.

I don't think the LDAP keys are really suitable for use as a KEYS file
at present.
