[CentOS] AWS ami are out of date / support restricted instance subset

Hi all,

the current AWS Marketplace CentOS7 AMIs (1602) are restricted to an
outdated subset of EC2 instance types (at least m4.16xlarge and x1.*
are missing). The AMIs are also based on 7.2.1511, which is now quite
outdated.

Are there any concrete plans to update the AMIs? Is this due to a lack
of time, or are there other roadblocks that prevent an update?

Cheers,

Kad
