sunpy: Using sunpy.map shouldn't require remote access libraries (e.g. aiohttp)

I am trying to create a frozen and minimal python environment for some code I run daily to output synoptic maps and magnetic connection predictions. Installing dependencies is fine - I can just use pip install --no-deps to ignore sunpy’s (extensive) list of dependencies that I don’t actually need.

Doing import sunpy.map however reveals a dependency on aiohttp that I don’t really want to have to install however. I am wondering if there is a way to remove this runtime dependency?
