In a code review a couple of years ago, I had to say "no" to a dev casually including pandas (and in turn numpy) for a one-liner convenience function in a Django web app that has no involvement with any number crunching whatsoever.
Coincidentally, Copilot has been incredibly liberal lately with its suggestions of including Pandas or Numpy in a tiny non-AI Flask app, even for simple things. I expect things to get worse.
There's a ton you can do with sqlite, which is in the Python standard library. You just have to think about it and write some SQL instead of having a nice Pythonic interface.
To push back on this, I consider pandas/numpy so crucial to Python as a whole they are effectively stdlib to me. I wouldn't blink at this because it would happen sooner or later.
Unless is was absolutely critical the server have as small as a footprint as humanly possible and it was absolutely guaranteed there would never need to be included in the future of course. However, that first constraint is the main one.
