I am not blaming marketing here. Real engineers never listen to marketing.

The main issue why BGP won in some MSDCs was that it was much easier (and
cheaper) to deploy on OEM white boxes then any alternative scalable IGP
(read use open source).

So yes - link state IGPs were late for MSDCs. Petr's draft then RFC was
like a hammer to this as well. But many use BGP as an underlay without
fully realizing the pros and cons. Some run BGP purely from positioning
perspective as they can be seen "weaker" as the largest hyperscalers. Many
still run BGP services with no hierarchy and clean decoupling.

IMHO even for many DCs this is still not the lost battle if positioned IGPs
right. So let's progress this as Experimental and clearly explain the
benefits if given implementation supports this.
