Some clarifications on Mage Hand

[Kurald Galain]

Once again, even if you can step on it or interact with it, it can only exert 20 pounds of force, which is going to be significantly less than what you're going to apply to any handhold or foothold while climbing.

Of course. That's why the bonus I suggested is substantially less than that of, say, actual training in climbing (i.e. +5).

Giving bonuses for good ideas is what I consider good DM'ing. Arguing that by real-world physics that probably might not actually work doesn't make the adventure more fun for the players involved.
