Why was support for old server protocols dropped?
The problem with keeping support for rather old protocols is:
 * It causes network-wide issues. For example, the SID/UID protocol extensions solve many desync issues that result from nick collisions. When at least 1 server does not have SID support then it negates these fixes.
 * It clutters the source, because you now have many exceptions to the rule
 * It causes bugs, for the same reason, and also because code for such older protocols is undertested
