It's a bit like saying 'let them fly on private jets' and someone pointing out that only a few people in the population can afford it. Doesn't imply that private jets are useless, just that their use is limited.
Ah yes. I have the time and the knowledge to "just" remove that code and "just" build that version. When even the simplest libraries can't usually be built using the instructions the authors leave for them (if they even do that)
You don't have to remove the code, you can just pin the version you're using and go for quite some time (sensitive to security context). Most builds are pretty easy to do with 5 minutes of following instructions or whatever build tool. I did this exactly thing with termux (an app I relied on) when they removed sending sms due to a google rule change.
Also, you only have to do it if you're the only one left. Chances are very good that there are others in the community that may step up wholly or in part. Sure the risk is non-zero, but the point of freedom is that you could if it came to that.
