> Having access to the source

Yes, thats great.

> being able to land a diff to fix the issue is awesome imo.

yes, if its a one off. but for my last project that would involve spinning up many "XFNs" (multi-team chat fests) to argue that actually they don't want to have that change because of reason x,y and z.

At which point you just give up and make a stupid fucking hack.

So much is not about engineering excellence, its about trying to get people to accept change.
