The problem is not that you wanted these features to take time to accomplish, the problem is that because you've made these features cost premium currency to upgrade, players who have more access to spending real life money will have a large advantage over players who cannot.
They can cook more food to either sell, or use more energy other places on the site, they can mine and smelt more at once, etc… Do you not see this a problem to both the fairness to your entire playerbase and the overall longevity of the game?
If you wanted these features to be locked behind a time gate, why didn't you do it elsewhere? Such as making these cost a different currency which can be gained through that week of grinding that you described. Or, again, making them locked behind profession level ups. This would greatly increase the justification behind having profession levels at all, as for many professions it seems pretty barren.
It's really concerning that it seems your goal continues to be finding ways to ease people into spending on this game. A lot of the monetization of the game feels very predatory in a very “mobile gaming” way. It's really disappointing to see that you're continuing this trend.
