What could help here is if changes to libraries, i.e. functions in discourse/lib and discourse-common/lib, are treated with a bit more caution and notice than other changes. Typically it is a change to a commonly used library that catches one of my plugins, the most recent example being the change to buffered rendering that also effected @cpradio.
Generally speaking, I am confident that things are moving in the right direction in this respect. Just a few tweaks to how more systemic changes are notified are needed perhaps.
