Indent files from plugins are already loaded by default. Isn't this working for you?

for me there were cases where you can have multiple plugins with indent rules. For example, eclim and vim-javascript both contain javascript rules, however vim-javascript is far superior for me. The old method always resulted in eclim loading for vue files.

The other suggested fixes for using set ft= html.javascript or vice-versa worked, but also broke completion and other plugins.

get() was being used here to return -1 (which means "do not change the indentation") when the indent file for that language is not present.

Honestly I couldn't tell that this actually affected anything when I changed it-- tested it with missing indent files
