I think it could be useful, yes (I like the look of the libertinus
font, in particular in combination with the biolinum font; it is
probably worth trying to get the math font to work as well as
possible). I think there were some problems with accents and such, but
not too big. I think you could try to use it and see what you think.

I put it on my todo-list to download the new version and to run some test files.

I could also mention here that in the upload Hans did some days ago,
most changes are "behind the scenes", so the user should not really
write their code differently. One exception:

In integrals, texers have usually a \, in front of the differential.
Now there is a differential class, and the macro \dd will give a
differential d, with (hopefully) correct spacing. Thus, write for
example \int_0^1 f(x)\dd x.

If you find any strange distances between atoms, please mail me
examples. With the introduction of new classes, there are many new
pairs, and perhaps not all of them are setup "correct".
