Except that Interledger is not a "random third party", it's a protocol: https://interledger.org/
So that you can make payments to someone else regardless of whether they want to use Bitcoin or not.
I believe Interledger is the right level of abstraction for this, in the same way that you wouldn't want your email server to have to know or code against the lower protocols, e.g. Ethernet or WiFi, but only IP, TCP and SMTP. This way your email server can EHLO any email server, regardless of the network topology or underlying protocols.
Ok, so my bitcoin address is "bitcoin:1PQLtWnjUi1itHLG6QCQeHM3Nxua8pRsq1". What tag do I put in my HTML in order to receive payment from this system, without having to sign up anywhere?
The documentation for Interledger appears to be for people who want to build software, not for people who want to send or receive money. And it talks about setting up accounts with xpring.io or rafiki.money.
I see no evidence that Interledger can be used for receiving money without having to set up accounts or run software. Plenty of evidence to the contrary.
As I said before, to receive bitcoin from one of these systems, there is nothing I should need to do other than advertise my bitcoin address. Anything more than that, and the system sucks.

Interledger does the same for payments.
