The problem you're describing is more about your choice in stack than brotli. NginX solved this problem with dynamic modules. I would argue that compiling your own software is a core part of servers and apart of running any service on the web that you are developing custom software with. It should be an automated process with release schedules the same as anything else, because not knowing how to build your stack will become painfully obvious when the 'official' releases have a problem.
