I don't think so, if you assume that learning is a linear thing and at the end of it you improve as a dev. But the problem is that learning isn't one curve, it's a bunch of them and most of them lead to dead ends or even turn backwards after a while. If you bloat out a language, what happens is that some subset of devs (like, maybe 10%) write really great code and have all the tools they'll ever need to do so. And the other 90% learn a chaotic mix of good and bad practices from each other, without the ability to properly distinguish them, and eventually reach some local maxima amongst themselves of overcomplicated "average" code that's shittier than I imagine it would be if they just kept the language simple.
