It'll be end of 2018 for general available software on the majority of
platforms - and for a company like NTT, a deployment of configurations
that use large community are likely to be in 2019 or maybe even 2020.
I don't intend this statement as a roadmap announcement, but rather to
illustrate the timescale.
I'm tracking large community support here: http://largebgpcommunities.net/implementations/

yes, there are real-world issues for 32-bit ASN users today related to
communities. If I'd have to do a greenfield deployment of a new transit
network today, using a 16-bit ASN would be a blocking requirement due to
BGP communities. I imagine that for a number of years to come 16-bit
ASNs will be more desirable than 32-bit ASNs.
