How do we juggle multiple LSPs?

[unphased]

For example I'm tempted to use multiple Python LSP engines (pyright and ruff and pylsp for example).

First, I found that the way I was doing my binds was causing the go to definition to go twice, and this is because two of my LSPs configured had the definition to go to, so technically this wasn't a bug.

I set this bind in a function which is given as on_attach to require('mason-lspconfig').setup_handlers' default handler:

local lsp_attach = function (x, bufnr)
  local engine = x.name;
<...>
  vim.keymap.set('n', 'gd', function ()
    print ("gd called", engine)
    telescope_builtin.lsp_definitions({ jump_type = "split" })
  end, ext(bufopts, "desc", "Go to Definition(s)"))

(where ext is

local ext = function(table, key, value)
  local tbl = table
  tbl[key] = value
  return tbl
end

)

I haven't quite exactly produced the logs that prove to me that it's doubling up on key binds that was causing the behavior I saw of opening the definition in a split twice, but... well, it did stop doing that once I uninstalled pylsp. Anyway, I think it's fair to say that we do need to get creative in order to cleanly enable multiple LSPs whose functionality overlap. So far I am digging the stacking of diagnostics in Trouble.nvim and stuff like that so I'm leaning towards trying to see if it's possible to dual/triple-wield LSPs.

What are some techniques to do that? Should I just try to use a simple lua table to keep track of the number of LSPs becoming active for a buffer and start assigning some different keymaps so I can choose which LSP server's gotodefinition to use?
