I'm trying to do the same, keep the files, when I go to previous step. @trottera did you get a solution?

I think that is for the "md" prefixes deprecation and the compatibility mode [https://github.com/angular/material2/blob/master/CHANGELOG.md#deprecation-of-md-prefix](https://github.com/angular/material2/blob/master/CHANGELOG.md#deprecation-of-md-prefix)

Any plans to develop this feature? It would be very useful

Any progress on this? I can't find any reason at first to remove the attributes on reboot
