LSP only applies to programming languages and specific configuration files, it's useless when you edit files such as JSON/YAML/etc.

indeed. LSP are for high latency, high impact, careful changes. multicursor edits (with sublime for me) are for those "replace all the str_something with string_something in the next 3 lines, quick"

There are LSP servers for YAML (and by extension JSON)
