static libssl1.1 depends blocks openssl removal

d/control of memcached has this

 18 Package: memcached
...
 22 Depends:
 23 adduser,
 24 libssl1.1,
..
 29 ${shlibs:Depends},

This package builds fine against openssl 3 [1]

And it picks up the correct dependency via #29 shlibs:Depends
=> libssl3 (>= 3.0.0~~alpha1)

But due to the static listing of 1.1 it effectively holds both:
 Depends: adduser, libssl1.1, ..., libssl3 (>= 3.0.0~~alpha1)

Check why it was added statically and likly just drop that entry as the shlibs seems to work.
