^True, this.
But, as I mentioned in an earlier thread, this is why they should bring specialists back. If you're going to foist more of the ETLs' duties onto TLs (& demanding that they have degrees), specialists could siphon off some of the TLs' duties like sales planners, scheduling, etc. TLs would still need to be responsible for disciplinary & administrative roles but much of the task work could be shouldered by specialists. It would also showcase who has leadership potential at an earlier phase. It would also be more realistic for a spec to consider working toward a degree if they knew they were being groomed for the future.
