Sure, having competing standards isn't always a good thing but we're not talking about a standard here. It's a new router firmware distribution and I think having more of them is a good thing as it gives people more choice.
The major problem that I do see here is that LEDE has been forked from OpenWRT, but has nowhere near the level of device support that OpenWRT has. I have a TP-Link WDR4300 which I bought specifically because it was one of the routers which are highly compatible with OpenWRT. However, LEDE doesn't list this router amongst its supported devices (though there are newer WDRXXXX devices listed).

What list are you looking at?
LEDE does builds for the WDR4300, and given that it's an ath9k router, it is and will continue to be very well supported. The only caveat is that I don't know whether they've added the necessary signature to allow the firmware to be accepted as a valid upgrade by recent TP-Link stock firmware, but once any third-party firmware is installed, there's definitely no barrier to upgrading to LEDE.
