On the point about technology lock I've thought that the move to microservices would mean allowing different programming languages, but whenever I've asked existing companies if they would be open to other languages it's usually a no. Part of it seems to be decent enough reasons but I usually think they could be overcome with a reasonable amount of work where the tradeoff may be worth it. I usually suspect it's more social reasons. My company also made the move to microservices and I was able to use another programming language but there was strong social pressure to conform.
