Not really. Generation numbers are discussed as a performance
optimization, but they're not unique, even within what we usually call a
"branch" (i.e. the set of commits reachable from the ref) :

A --- B
 \     \
  C --- D --- E <--- master

Commits B and C will have the same generation numbers. I hardly see a
context where they could be used by end users as commit identifiers.
