Those are pretty nasty workarounds and shouldn't be necessary. And
depending on what you're using such textures for, (eg. spec/bump maps)
even with blurring it can still cause temporal aliasing - flickering.

The main problem is that none of blender's textures (other than image
maps) are properly filtered/antialiased. For some like clouds, blend,
maybe others, it should be possible to do 'analytically' or via fading
off higher frequencies etc, for other more complicated ones perhaps
oversampling the texture itself could be an option (as opposed to
oversampling the entire shading in the render). Regardless, this is a
problematic long-standing issue in Blender, that it would be great to
see an enthusiastic coder work on - perhaps a good project for someone
new looking to get involved.
