Why do some tube-based power amps have back-panel replaceable fuses and others don’t?


I don't have a clue regarding this question, but I would like to know from the experts out there.  Obviously a design decision, but is it preferable to have one, or not...or…it depends...?

I’ve owned many solid state amps with back panel fuses. BTW, I have never blown a fuse on any type of amp tube or solid state!
Only time I ever needed to replace a fuse was in an Adcom GFA545 and that was in the early 90's. Had to lift the lid to replace the fuse.
