I see that merit too, as when 'install' reads from stdin it needn't do 
the inode check. However, POSIX requires 'cp - X' to copy a file named 
'-' to X; cp cannot copy from stdin. Although POSIX doesn't specify 
'install', there is some value to having 'install' behave like 'cp'.

I suppose we could have install special-case "/dev/stdin", on platforms 
where /dev/stdin is known to mean standard input. Seems like a bit much 
to work around a Darwin kernel bug, though.
