Will namespace alias in aspx files be supported in RS 6?

Regarding RSRP-221520 - "Does not handle Import Namespace with alias in aspx page".

Is this planned to be fixed in 6.0? (According to youtrack it is not, but I think this might be a "critical" if critical means you give show an error while vstudio compiler does not)
I'm curious if we can ditch a "do not use namespace aliases in aspx files due to RS errors" guideline if upgrade to v6 when it's released.

Thanks.
