It is not legacy.  We are using it in 193/8 and 194/8 and currently we
do not intend to do differently in any new /8 we might start.  /18 is
just too much of an allocation for a garage with a couple of <your
favourite modem hub>.  We cannot and will not refuse to allocate address
space to such garages until someone comes up with a *resonable* policy
of what is an eligible garage.  I can understand that some sugest that a
reasonable policy is to require connections to a at least two <major
transit provider>, but I postulate that <major transit provider> can
never be defined in a rasonable way. 

So please define which garages shall be eligible for an allocation
and get the RIPE community to agree. Mind this is easier than the 
Internet community.

Folks: Here is an issue!!!!

My experience tells me that it is too big. We are not doing slow start 
long enough however to quantify that.
