A: The main thing is to point you in the direction of the problem. I'm old school too and take stuff apart to see what's wrong rather than just toss parts at it unless it's obvious.
Oh I agree, that's why I like to mentally catalog good tests! Cracking a bleeder loose is a simple test that tells a lot with little cost or effort. That plus a tiny bit of knowledge tells a lot. Like revving up an engine from idle: lights get brighter? Alternator working. That sort of thing.

If that 1 side loosens only, it could be the hose internally collapsing (any cracks in it?) If not, the caliper is bad for sure. If both sides come loose, then the master may need changing. Pump the brakes up till they are locking again and loosen the line at the master. If both loosen up, it's master cyl time!
Good test! Would not that also check if the check valves are still
installed? Bleeding fluid would release the residual pressure.
