I had been advised in the past by a mechanical engineer and competitive mountain biker that it is very desirable to have a through axle especially on gravel and mountain bikes.

Not sure what would be the issue. Opinions?
Advantages TA:
1. the axle and hub will always be in the exact same position. this is especially important for disc brakes
2. even when you put the wheel in in the stand, it will be in the correct position. for my QR wheels I always have to loosen and re-tighten the QR when the bike sits on the ground to seat correctly
3. on a QR the front disc brake could in theory push the axle out of the QR. this is unlikely, but may be an issue if you get really strong 200mm brakes and/or a bit worn or loose QR
4. The axle is hollow and has a larger diameter than QR = potentially lighter AND stronger.

As you see, most of that will apply to MTB and gravel bikes. Which is why they started there.
