Sure, that’s real logic there.
And as I stated... And of course, all of this is up to the individual.

Well perhaps therein, lies the proverbial “rub”. Why not do it anyway?
If the PSU is not going on the plane, train or automobile to get shipped to the other side of the planet, gluing capacitors to the PCB is not necessary.
Do not use any RTV: many silicones cure by releasing acetic acid, which will corrode the power supply.
And looking at the red-outlined area, the white-ish looking areas are where the thing remained “stuck” to the processor (green dots). While the smoother, dark grey areas (yellow dot) might represent where actual heat-exchange contact was no longer in effect. (i.e. baked and separated.)I removed everything and very carefullly also tried to clean the top of the CPU (although not too hard!).
Again, it would have been interesting to note the exhaust air temperature of your mini before replacing the paste. But big congrats on a job that many simply choose not to attempt!Thanks. The exhaust air temperature was not too hot before, although I this was just tested with a wet finger rather than a thermometer. Now you can barely feel any heat at all.
And I mean, that when you “fire” such desoldering pumps they don’t extend (shoot) that metal plunger out of the end “towards the board”. That’s only extended when you elect to push the “un-cocked” plunger down through the nozzle to clear any hardened solder out of that nozzle.
