I was worried about the same. I think it's a valid reason to sit back and wait. Especially if Numba works for you. I was also and continue to be worried about the tooling, the lack of good tutorials and especially the Type driven system. I like it so far but Object Oriented is a lot more familiar to many people. The library situation for me specifically has tipped to be a net positive. I also could transition my very small team off Python completely. So it was not an ad hoc decision, I tried it several times over the last year's and decided it's not there. In my specific situation, with a rewrite of a core library coming up and the library situation being there that changed early this year.
