It's ironic from what we're shown that Lana is more interested in being a mother figure to Kara than she is than being an actual mother to her toddler son who was shuffled off to Smallville to live with Pete. And it doesn't help that (thanks to stinky past stories about Lana's motivation in doing things like Chuck Austen's run) it may be surmised that a large part of Lana's interest in Kara is about her connection to Clark and Lana keeping that connection.

Linda however is a 20something adult whose connection to Clark and Lois is benign (in case anyone like Lex is looking hard) who already knows a different version of Kara (the one from the Silver Age she bonded with), has all Matrix's memories (and hence memories of the Kent Farm) and looks different enough that the two Supergirls would never get confused. Who would DC have us believe was the Supergirl character that pops up in all those 90s stories like the Death/Reign/Return of Superman if Linda didn't exist?
