Arbitrary modes in plugins.lsp.keymaps.lspBuf?

[mightyiam]

Seems like I had to use plugins.lsp.keymaps.extra instead of plugins.lsp.keymaps.lspBuf because normal mode is hardcoded:

mightyiam/infra@01aa0aa

Did I miss anything? Otherwise, could plugins.lsp.keymaps.lspBuf support specifying modes?
