The thing is, what you're asking for seems to be an extremely specified a-la-carte' menu where you would be able to order exactly and only what you wanted. I mean, lets say they did release an extended version of things like what you are asking for. Okay, obviously, it wouldnt be "fair" to prior DVD customers for you to get the EXACT articulations that *I* have paid a buttload of money for... So instead, lets say they offered some sort of slimmed-down version of it.
Lets use Orch Strings1 as an example. Lets say they whittled it down to include many (but not ALL of - as i mentioned earlier about "unfairness") of the Orch Strings 1 extended articulations... Lets say they offered a package which extended to you Glissandi, Con Sordino, all the perf-repetitions, all the extra dynamics patches, the fast perf-intervals, the scale runs, Fast Repetitions.. Lets call that the Bargain Extended Plus Orch Strings 1 package.
No matter how well this may suit exactly what you wanted, someone is going to come along and say "Why did you leave out the DYNAMIC Perf-repititions?!?! Why no Isolated Repetitions Resources?!?! Why can i get Fast Repetitions but no Upbeat Reps!!! NO FAIR!"
Then there would STILL be articulations that SOMEONE felt was unfairly left out and they would feel as if they are being strong-armed into buying the WHOLE DVD collection if they TRULY want everything. At what point do you draw the line of what is fair concerning how to cut everything up? I mean, taking your general request to the extreme, would you expect some sort of pick-and-choose system where one could specifically order a Performance Repetition Harsh Dynamics Decrescendo only for E5# only (3.99 USD)? One scale run on the Violin G string from D4 to D5 only (99 cents!) ? I'd like the Ponticello Strong Dynamics 2 Seconds for C3, E3 and F3 (1.99 USD per note = 5.97 total!)?
Im not trying to say you are implying such ridiculous dividing of articulations, but at SOME point SOMEONE is going to insist they felt left out and are being discriminated against because of what they have already previously paid for.
Simply put, VSL cant make a package that is 100% going to please EVERY single customer concerning every single articulation that they need.
