I don't think that model specifically can be adapted, but yes, it is a real problem and people should be thinking about ways to solve it.
The military example is probably instructive because that's a case where a long-term career in a given military is relatively common.
Figures from the last decade [0] show that half of all British Army recruits will have left after four-to-five years service, and only 23% make it to ten years.
One reason (not the only one) for the military emphasis on training is they can't fully utilise their skills in peacetime, unlike most other professions.

That makes sense. I attend conferences and the like which is training to some degree. But training in the sense of actual courses of some sort wouldn't be a lot of use to me at this point in general.
Crucially, as soldiers (non-commissioned) go up through their rank structure (corporal, sergeant, etc) they can take instructor courses back at the schools that qualify them to do on-the-job training back in their parent units (and which increase their pay). The best of these instructors may be invited to undergo additional training that qualifies them to become an instructor at one of the schools. So some responsibility for training is fundamentally baked in to career development.
