Media Delivery API ignore casing of alias?

[bjarnef]

I tried out the new Media Delivery API, but I noticed filtering by media type is case sensitive:

So this works:
/umbraco/delivery/api/v1/media?fetch=children%3A%2F&filter=mediaType%3AFolder&skip=0&take=10

but this doesn't:
/umbraco/delivery/api/v1/media?fetch=children%3A%2F&filter=mediaType%3Afolder&skip=0&take=10

because media type alias of folder media item by default is Folder.

Should it just ignore casing as Umbraco require unique aliases anyway?
