Well, the current RIPE policies state "you get the number of addresses
that you need to number your devices" (without that specific wording).

It specifically doesn't say "if you have special technical needs, we'll
graciously round up the numbers to 32+ times the number of machines that
you have" (/29 -> /24).  

Of course this is because the same rules apply to PA and to PI holders - and
we've told PA holders since 10+ years "no, if you only have 5 machines,
I am not going to give you a 'Class C', here's a /29, and that's all you're
gonna get!".  So changing these rules for PI "/24 for free, just say the
magic word!" is frowned-upon by many in the community...

But in the end, IPv4 just sucks, and I'm happy when it's finally used up.

IPv6 PI is a /48, no matter how big or small the company, so RIPE can 
nicely keep out of the "we can't give you what you want, so you lie to
us, and get it anyway" mess.
