If no request for GM support was made it is perhaps because it was obvious that Dorico would integrate it. Idem, nobody asked for writing septolet because it was obvious that Dorico would integrate it.
Did you know that musicXML uses partially GM standard ?
example for the standardization of percussion drum kit : http://www.musicxml.com/tutorial/percussion/multiple-instruments/
One of the standardization of GM was to put drum kit in channel 10 … (drum track is very complex, unpitched note have two pitch, one for the score one other for the sound … and musicXML use the GM standard with channel 10 and the two pitches for each instrument in drum kit)
And also for many other functionalities …
What is “Professional sector” ??? only classical musicians ? its the reason why actually you can’t edit drum track with Dorico ? (it’s a joke …)
I think that people who buy Dorico are all professional musicians. In the jobs of musics, there are many different activities and as publisher of notation software, you cannot allow to ignore certain occupations. I understands that you want to stand out as the best software of the profession, you deserve him very well. Dorico is the best musical notation software, At present it is still incomplete, but it is only a question of time !!
To shared files between various software of musical notations, musicXML (standard based on midi standard) is going to replace midi. But it still has a lot to do there. This standard is not still interpreted in the same way by all the publishers.
Even at Steinberg, cubase pro9 do not respect completely the standards of export in musicXML.
