In practice, in my experience, that is only an issue when using MIDI
clock for synchronisation.

The big disadvantage with USB MIDI, is that you can't connect two
devices, which only have a USB slave port. One of them needs to be a USB
host (with USB MIDI support). This role is normally played by the
computer. But you can't, for example, connect your digital piano with an
USB MIDI output directly to a hardware synthesizer, which only has the
same USB MIDI output slave connector (or only DIN MIDI). There are a few
keyboards, which have USB host functionality (e.g. Yamaha Motif, Korg
Kronos), e.g. you can directly connect another USB keyboard to them, but
the vast majority of USB MIDI devices doesn't.

DIN MIDI also has the advantage, if you accidentallly pull out the
cable, the MIDI port in your application (ALSA, JACK, whatever) doesn't
go away and doesn't needed to be reconnected. On Windows you often even
need to restart an application to recognize newly/re-connected USB MIDI

(Of course, if you have an USB-MIDI-adapter built into a cable, it's
basically like a direct USB connection.)
