Clearance and rounding in kicad-nano


I've got these issues when routing a board. Let's say I'm doing
a 0,2/0,2mm routing (i.e. 0,2mm of track separated by 0,2mm of
clearance). Which is huge by today standard (in mil it's about an 8/8)
but the numbers are easy :D Grid is set to 0,05 as for IPC
recommendations (also it's a good general purpose grid).

Now, the issue is that you *can't* put the tracks at exactly the
specified distance (DRC during track drawing rejects it). In fact, the
'stick to wall' feature (no better name for it, when you 'push' the track
against another one) gives the following results:

Po 0 30.8 15.9 30.8 20.1 0.2 -1
De 15 0 1 4FE19D7F 0
Po 0 31.200002 16.05 31.200002 20.100002 0.2 -1
De 15 0 2 4FE19DC4 0

Yes, that's 2 nanometers away :D these 2 nm anyway break the 'grid
beauty' and are unconvenient anyway (you can't route adjacent tracks
without the stick to wall feature).

What's the plan for this? I suppose I could set the clearance to, say,
0,199998... I mean, there should be a better solution, IMHO
