This is still the case.

I decided to give this a go, and is almost ready to push migration to
version 4.5.5 to salsa.  It will happen this evening.

I believe it is best to move directly to 4.5.5, change the SONAME and
upload to experimental.  Uploading to unstable might need some
coordination with the reverse build dependencies.

Sadly upstream do not so far care about SONAME and backwards
compatibility, so we will have to pick SONAME on our own.
