I don't think this is a meaningful limitation any more. Go's ecosystem is big enough - I've been using it for a few years now and have only found a few esoteric things that aren't supported (and nothing big enough to be a showstopper). The quality is also really good; I've been impressed by many of the libraries we've picked up. Especially in light of vulnerabilities like log4j or that similar Struts one Equifax had a few years back, I'd much rather be working in the Go ecosystem than Java's.
