When trying to compile on Raspbian (debian) Stretch, I am not able to install all the deps:

glib >= 2.54.2 is really a show stopper on this distribution afaik.

I would indeed not install a glib different from the distribution one

system-wide (on any distribution), since it is low level and widely used (and could break other programs), but it is easy to install it in a custom prefix and have GIMP only use this version.

Unless you mean that it is impossible to build glib 2.54.2 on Raspbian. In this case, I have no idea (but this may be the occasion to fix whatever needs to be).

About the midi problem with the flatpak, it is kind of documented here, so it doesn't look too good for me: https://github.com/flatpak/flatpak/issues/12

Yes the MIDI support is not built in GIMP on Flatpak. And you should not expect this to work any time soon (I mean, it may happen any day, who knows?! But it is quite some work and it doesn't look like anyone is really interested into this).

I did not answer on this in my first email as I was unsure you were really asking about this specific feature (you did not ask about this in the body of the email, only as a short mention in the title). :-)

Not an expert on the subject, but when using snap you can add permission using interfaces:
https://docs.snapcraft.io/reference/interfaces

This is the same thing for Flatpak, but someone needs to implement the

said permission first.
In the case of this specific feature, it would require someone to implement the said portal (possibly several times, as it may depend on the desktop for instance; don't know if this is the case here), then someone to re-implement the feature in GIMP instead of using libudev (which is how we currently implement this feature, but this won't ever work; libudev won't likely ever be usable in a Flatpak sandbox).

So the question is: anyone using gimp 2.10.4 with midi support on rpi3?

You won't find anyone, this is currently not possible.

If having this feature is a blocker to you, then yes, you have to install GIMP some other way, either by building it yourself or waiting for the distribution to get a GIMP 2.10 package; I saw that Debian Testing just got GIMP 2.10.2. This should reach Raspbian at some point. :-)

It isn't a show stopper. You can install GIMP and its dependencies to a directory within you user account and run it from there. You set PREFIX to the be the path to the private directory then use that include a reference to the path in both LD_LIBRARY_PATH and PKG_CONFIG_PATH.

Cheers!
