This is the opposite of how I see it. There's really nothing universal about flags, especially short ones, in different random utilities (what's -n mean? -f? file, filter or force?). Whereas in Powershell since there actually is some standardization, your knowledge about what -WhatIf or -Verbose do is actually pretty leverageable. And more powerful with the ability set default parameters and so forth. And the discoverability and help in Powershell is also standardized.

So I get why unfamiliarity would make it not worth it to switch from whatever shell you prefer, but I don't think I can see your point about flags.
