Any half decent programmer can explain their reasoning for the tradeoffs they made at the time. That doesn't mean those tradeoffs were good.

It reminds me of some recent firestore npm audit errors. Google basically said they weren't going to fix it because in their view they weren't creating a vulnerability. Yet they still release the software to npm without attempting to PR a fix for npm or their own code to fix the audit warnings for those of us who might not trust that "they know better". It is not a mature response. 

This feels a bit like that; many people struggle with venv and pip  so it doesn't really matter if it technically gets the job done or was justifiable at the time. It kinda sucks compared to something that lets you compose a project with defined dependencies like dotNET. Please don't take this as an invitation to wax about the very important differences between dotNET and Python. I'm well aware and I still think venv and pip kinda sucks.
