to prevent from loading them on startup.

Thanks for the changes!

Thank you too.

Please consider similar change in

nvim-surround/lua/nvim-surround/config.lua

Lines 870 to 876 in dca2e99

	local buffer = require("nvim-surround.buffer")
	local nvim_surround = require("nvim-surround")
	vim.on_key(function(key)
	if key == "." and not nvim_surround.pending_surround then
	nvim_surround.normal_curpos = buffer.get_curpos()
	end
	end)

I didn't move those requirements into on_key callback because I haven't checked whether it can significantly affect performance.

I think that it is probably fine to leave those imports as-is, since by the time the user has called setup it is probably fine to import the rest of the modules. Also I don't think nvim-surround does a lot of computation up-front anyways, so I'll only consider changing it if someone demonstrates (i.e. measures) it to be an issue.
