So, is this planned for the 22.04 release?
Back in 18.04, there was a similar abi-breaking change between 1.0 and
1.1, and the resulting conflict between the libssl-dev and
libssl1.0-dev packages was quite painful to many people and never
actually resolved:

I would hate to see that happen again in 22.04.
