git-am is about patches in mailbox form, not plain patches, isn't it?
In that view, it's not a replacement for git-apply.

How about we start deprecating the old behavior?

1) add --no-index to force git-apply ignore .git, --git (or some other
name) to apply patches as if running from topdir, add a config key to
choose default behavior
2) when git-apply is run without --git, --index or --cached from a
subdir and the said config key is not set, start warning and
recommending --no-index
3) wait X years
4)switch default behavior to --git (if run inside a git repo)
