Bitkit supports LNURL-channel for loading channels from other sources than Blocktank (you could buy from LNBIG, for example).
We also started the LSP Spec Group, which now includes many industry peers working on standards for connecting to any LSP... all so Bitkit users can have options.
Also, ALL liquidity is "stuck" with your counterparty, regardless of whether it is an LSP. End users aren't supposed to have 10 channels, that doesn't scale.
