Hi, A simple list with all Bukkit versions compared to their NMS versions. 1.7 1.7.2 ~ 1_7_R1 1.7.5 ~ 1_7_R2 1.7.8 ~ 1_7_R3 1.7.10 ~ 1_7_R4 1.8 1.8 ~ 1_8_R1 1.8.3 ~ 1_8_R2 1.8.8 ~ 1_8_R3 1.9 1.9.2 ~ 1_9_R1 1.9.4 ~ 1_9_R2 1.10 1.10.2 ~ 1_10_R1 1.11 1.11.2 ~ 1_11_R1
This really doesn't matter to most because they usally make their plugin universal and just upload each separate version.
... Lol But anyways, the real reason I think people don't really care for these is the fact we use IDE's and the pop up as soon as your start NMS with the correct server jar.
Exactly, also usally when your making a plugin you should know what version you are making it in(most cases the latest)
Still, people wanting to support multiple versions need to know which craftbukkit version they have to import for each NMS version.

Or they could support several versions at the same time? https://www.spigotmc.org/wiki/nms-on-different-versions-without-reflection/
