No, and no.

The answer to "Is it left alone?" is "yes".

Wireshark will install WinPcap, but that doesn't replace existing 
network adapter drivers, either.  It does install a driver, but that's 
not a network adapter driver, it's a driver that plugs into the same 
framework that network adapter drivers plug into (NDIS), so that 
WinPcap's driver can connect to the network adapter and receive packets 
from it.
