You can, but at some point things start breaking down. Your dependencies are all outdated and pile up CVEs (which you probably are contractually obligated to do something against.) The dev-tool extension is no longer maintained, and Sentry stops support too.
You want to improve things by migrating to the new version or competing framework, but that requires lots of toil, since a lot of things changed in subtle ways or are done differently now, and that has ripple effects. Before you know it, you’ve spent four months playing the zero-sum game of rewriting your frontend. Finally you’ve made it, and then they release Tailwind 4.
Coincidentally, I just migrated something from Tailwind v3 to v4, even though Tailwind isn't really much my cup of tea. The migration tool that they ship was able to do everything. e.g. I ran it, then my project built and worked with v4 instead of v3.
Likewise, there haven't really been any major API changes in React lately either, but if you want it to be automated, they ship react-codemods which will handle a surprising amount of edge cases for you when upgrading.
