There was a time obtaining a solder type BNC connector was easy. The kit
of about 9 individual bits assembled with a solder iron and a spanner,
the choice of using 50ohm or 75ohm, different types to suit your cable
diameter. The warm feeling got when ya knew that the centre pin was
definitely soldered and none of the electrons would deteriorate on their
journey.

I've just been looking through Amazon and eBay, doing an RG59 75ohm job.

All I can find are crimp/compression/twist types. Horrible. That centre
conductor ain't secure.

What happened??

I could say you could have looked harder in your search :-)

This is one of the first hits in a search for a BNC 75 ohm connector

Photo 2 of the centre pin mentions solder. I'm sure most centre pins
could be soldered, even if they were designed to be crimped.

YMMV
