Finer grained control on caching

I posted and idea last week to Ideas and Feature Requests: “Finer
grained control on caching” (Finer grained control on caching),
but since I’m new to this forum/mailing list I have no idea if anybody
saw this.

I want to find out if this is an acceptable feature request and if
anybody else sees the benefits of this.

Short summary:
Add a new directive fastcgi_cache_key_suffix
Construct the caching filename like this md5(fastcgi_cache_key) . ‘_’ .
