Roughness Level

As far as I can understand the roughness level can be set from 1 (non-reflective) to 0 (maximum refections). It can be set with 0.01 increments.
Is there any possibility of making it a bit more flexible? I have attached 3 screenshots of countertop reflections with 3 roughness settings (0, 0.01, and 0.1)
You can see that between 0.01 and 0.1 there is not that much visual difference. The difference between 0 and 0.01 is very noticeable.
I’m trying to get something between 0 and 0.01 level.
Thanks!

Sorry for the late response.

The roughness 0 is treated as a special case - a mirror-like reflection that uses a light probe that is not blurred at all (6 images each with resolution 512x512). Any higher roughness uses a lower resolution blurred light probe (6 images with at most 128x128 resolution). Even if we allowed the editor to set tiny roughness levels (like 0.00001) with current approach the difference from roughness 0.0 would still be significant.
