I would caution against using LCSC chinese ICs in general, the fact that they are available now does not mean that they will be available 6 months later.

This can work for small productions where you’ll be stocking the full production beforehand, but for open source projects it will be a lot of lost resources.

Other than that, I don’t see any reason for NOT putting 20 year old ICs on boards (as long as they are not on EOL or NRND status). Yes, some newer parts have better tech, and they should totally check them out, in the end is about finding the best fit.
