I wasn’t aware that anyone here was advocating that.

I think you’ve got this thread confused with the one about Jinx, which uses the Enchant library for spellchecking.

In this thread, I have said that I believe that we could benefit from LanguageTool offering some IPC mechanism other than TCP.

OTOH, AIUU, Ihor believes that, rather than running LanguageTool persistently, it is tolerable to exec “java -jar languagetool-commandline.jar /path/to/file/to/be/checked” on each occasion that you wish to check some text.  The downside to this is that it takes many CPU-seconds for it to initialise before it can do any actual checking, and you pay that initialisation cost every time.
