The only drawback I can see would be if the coax were hanging down and
swinging in the breeze - the solder could develop metal fatigue over
time. On the other hand, the coax should be strain-relieved anyway,
else it's just holding on by the four holes and the center conductor.
Not much better, if at all.

It's not holding by four holes, but by being screwed by the jacket.
Screwing the connector body onto the coax jacket provides weather proofing and
mechanical "connection" between the cable and connector. What you did is to
expose the watersucking braid to rain and braid will eventually break off at
the junction of braid.solder/braid (tiny hair wires). If you never use the coax
outside and don't rock it, you might be OK.
But can you picture "horrible" impedance jump because of your action? Cecil
will never forgive you!
Kinda we were all stupid for all those years doing it the other way? :-)
