Sadly it's not really that simple (speaking as someone who has shipped JUCE apps on iOS and Android) – sure, the code might compile on every platform, but in reality there are still a bunch of other factors that can make stuff not work, or perform badly, or complicated to test, or whatever. I suspect really it's that companies are not willing to do the testing or support required to say they support Linux.
There's major Linux progress and I'd expect more to come soon. JUCE 7 introduced LV2 and I think more developers will release to Linux sooner than later.
It's the first I'd heard about it, apparently it happened in April 2020.
Kinda weird that PACE works with intellectual property and licensing, and not in audio software development themselves.

As PACE’s tools are used by a large number of world-class audio software publishers the company understands the importance of JUCE as a foundational piece of industry software infrastructure.

A lot of their customers use JUCE, so there is a connection even if not very strong.
What is also good (in my opinion) is that they are not a big player of the audio software. If JUCE had been acquired by, for example, Steinberg, I would be very worried.
