This was the end result I came to as well after the bigger frameworks started gaining popularity. I work primarily solo in a single organisation with server-generated (CMS driven) websites.

Yes, I could have replaced jQuery with Vanilla, but the syntax for jQuery is still so much simpler, and I care about my limited time and productivity. For me to switch over to something like React would be complete overkill.

Again, as part of a bigger team, like you, I'd most likely consider a different approach.
