Heating disturbs the wire's plastic insulation, which provides a
significant amount of strength and resistance to sharp bends.

Oh please, the last shred of insulation at the end of the wire
provides near zero additional strength, and besides:

1) The cable itself ought to be clamped before entering the strain
relief.

Agreed.

2) If you're melting the insulation you have either crap wire or no
soldering skill whatsoever.

Agreed.

I have *NEVER EVER* had the actual solder joint or copper wire near it
fail in any of the hundreds of leads I've made over the years.

I've surely had it happen with soldered leads assembled by others.

the only failures I have ever had have been fracturing of the wire *after
exiting the strain relief*,

I've seen that happen, too.

and even then only after a good long service life. (ok so the occasional
one had a dry joint too, no-ones
perfect)

Work with enough cables long enough and you get to see *everything*.
