It will take twice or trice longer time when _all_ packages with ELF
files will get their set-versioned dependencies, so I expect apt-get
startup will eventually be about 10x slower again (compared to 5.1 branch).

apt-rpm indeed calls rpmRangesOverlap() too many times, it's common
knowledge.  Unfortunately, stating this fact isn't sufficient to make
apt-rpm work faster.
