Setting company-echo-delay to 0.5 instead of 0 will help reduce unneeded
and intrusive code-completion popups while in the middle of typing. It
seemed like a good idea when I first set it, but after some use, no
thanks.
The whitespace-style tweak, effectively removes "indentation" from the
list of items whitespace-cleanup deals with on save. Indentation is
already being fixed by lsp-mode's before-save hooks, and
whitespace-cleanup was not very intelligent about it. It specifically
replaced all instances of four consecutive spaces in raw string
literals with a tab, which caused issues with multi-line raw strings
containing JSON.
