Indeed, and agreed. I've got a number of large, multi-national enterprise customers who are in this very situation, they need the options because they're trying to get away from a lot of nasty, inherited, legacy configurations. The only way they can safely migrate from those is if we (well, IETF, via RFC, and then vendors) provide them the options to be flexible.

This thread is somewhat like the DLV/DNSSEC thread on dns-operations. Some are arguing DLV should die, but frankly it's giving operators options to *migrate* to DNSSEC rather than making forklift changes in their networks.

I'd simply like to see the option of doing RA, or not, or DHCP with option.routers, etc.

Indeed, again. I stopped going to IETF (for good or ill) in 1997 or so, but still following the mailing lists. I haven't been since, but sounds like this is still the status quo.
