Thing is, of the 95% of arranger not used for gigging, probably 95% of THOSE are used by people with insufficient technical skill to DO all the extensive tweaking, translating, setting up VSTi libraries, etc., etc. an open arranger NEEDS. Heck, a fairly high % get used by people who can barely PLAY, let alone know a damn thing about programming.

Sorry, but I just don't buy it... Just because you have the TIME doesn't say a damn thing about whether you have the skill. For one reason or another, the VAST majority of arranger players don't have what it takes to use an open arranger. Thing is, as always, if one of the manufacterers took the time, got off his fat arse, whatever, and set the damn thing up so that at least OOTB it bettered the closed arranger, it would sell like hotcakes. But rather than provide TOTL sounds and styles, they are sold as 'kitcars' and you build it yourself. As I have been saying forever, 99.999% of people just want to BUY a car to drive around. They DON'T want to have to build it first.

Just face the facts, guys. You are a TINY, tiny minority of arranger players, somehow thinking that your way of doing things is commoner than it is...

You've acknowledged that gigging arranger users are in the minority. Now take the next step...
