The FM9 has a 3rd physical jack so it was not deemed necessary, one pedal and two switches being the sweet spot.
Understood, yet @Prince question still remains: Is it a hardware-exclusive thing or a function that can be added later via firmware? My particular use case scenario involves one Mission Engineering pedal for Wah and one EV for Volume/Whammy/general expression, then it leaves me only one jack for a switch. The dual-switch implementation I like is one dedicated tap tempo and one "utility" per-preset switch (particularly a momentary switch to toggle certain effects i.e Intelligent harmonies during a very short passage, Dive bombs, a Virtual Capo when I only need a "Virtual 7th string", a Delay on just a note or group of notes during a passage, etc...)
I know there are 9 switches available in the FM9 for my needs and that they're road-worthy but the beauty of those external switches is that they're are so cheap that I wouldn't mind replacing them every now and then for that kind of application where my heavy foot will be smashing the hell out of them.
Again, it's not a deal breaker and you could see it as a complaint, but as I see it, it was a superb feature on the FM3 and it would seem natural to make its way to the younger-yet-bigger brother, I even asked if it could be ported to the Axe-FX III and got no answer at all.
