Base Camp is good because it follows POP's "time gated" mechanics. And the ability to let the players to dictate how many workers to assign to get specific resources further gives more powers to the players.
RS3 is about powers and choices to the players. Good design.

"Mobile-esque trash" POP is loved by the players... because it is not mobile-esque trash at all. It is just some nice offline minigame that give big rewards and powers to the players.
If Base Camp is not a similar offline minigame then it would be just another piece of grindy trash.
I'd personally rather grind content in three weeks than continue logging in once a week for nine weeks.
You can still grind content in three weeks at your discretion while you are doing the Base Camp. The mechanics of Base Camp is not any different than POP. Both of them give you EXTRA optional content and rewards at the expanse of just a few minutes a day.
