sure. i get what you mean and here in the US it is the same as well, the people that play can be rockstars too as well as wear the producer hat if they want to. Butch (Vig - Garbage) was already a busy producer before he even went huge with Garbage and the same goes for Steve Albini (producer for Nirvana, Smashing Pumpkins) who also plays with avant-garde punk outfit, Shellac, and Amir Derakh (Orgy, Coal Chamber) and Adam D (Killswitch Engage) who has produced quite a number of new metal bands out right now like As I Lay Dying, all Killswitch's albums and Shadows Fall. Devin (Townshend) from Strapping Young Lad is another gifted guy that actually runs his own studio out of Canada and tours when he can with his band. point is, people who occupy the producer seat and the musician's role usually do so because it allows them to contribute and develop their skills over a broad range of situations which makes them very savvy about what they do and how they conduct business in music.
if you asked me, i would encourage being a producer as well as a musician because it really shows you how the creative process goes from the writing stage to the production level. as a musician, it is your responsibility to know everything about your craft. when I moved to the US, a lot of the people on the underground scene I got to know started their bands with a DiY operation and eventually produced their demos this way with borrowed gear and, quite often, borrowed instruments. All the bands I used to know on the touring circuit from the late 80s and early 90s in the underground have since moved on to being pretty popular bands in their own respective genres and every single one of them have done so knowing how to work behind a console as well as on stage with an instrument.
