For me, it works as well on nightly without any modifications as it did when the archival announcement was made. But I only use formatters and one or two linters. So can’t confirm for other features.
That said, I am thinking about changing to conform.nivm for formatting.
LSP maybe portable with it’s config if the LSP themselves are independent. Checkout Mason which seems to make it easier to bundle neovim and “portable” LSP. There was another project similar to Mason with some more features, but I forgot it’s name. So search around to see if that fits your requirements.
