Maybe people have been "begging" for it - I never personally noticed it among the many things people have been clambering for - but even if, you think those same people wanted a simplistic, space magic solution that undermines the base principles of the game?
I doubt it...
So, again, there are many features the game is apparently not yet ready for, so drop them for now and use the production time to get the game there!
I would prefer to have it now and fix it later, given my realistic options, and as stated, it only undermines base principals when you don't bother to explain it for yourself and or blatantly abuse the system. There's no reason it has to have a startling effect on your own personal experience of the game. Sure, you can call the perfect ship to you to take that mission you really want. I won't be bothering. Sure, you can exploit it to take one or two jumps off of a longer trade route. I won't be bothering. Furthermore, I see no reason to care if other players decide they do want to do those things. Yeah, unfortunately for those who enjoy ganking traders to no end those traders are going to be able to swap to their favorite combat ships and come after you, but I don't see that as a bad thing even as someone who will target players while undermining.
