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...?

It’s more expensive to have a back panel fuse rather than one on the board. Obviously easier to replace. Some manufacturers may not want you replacing a fuse as it can signify a major issue that requires service.
