This is an interesting development. Electrum is a Simplified Payment Verification wallet (i.e. not full node). When it comes to LN, a full node is usually required due to the "honesty enforcement" required to operate LN. I wonder if this is now possible due to the recent development of watch towers. Very cool that LN will become more accessible.
True, but you can set your own Electrum server (ElectrumX)
