I agree with this but there are already 2 different schemas to fill the 
same thing, why create a 3rd ? wouldn't it be more reasonable to use 
maxspeed:type=default or =unsigned or =nosign for example ?

I agree with this point, any preprocessor is able to known that every 
maxspeed limite in a country is related to the default value of this 

that being said, the whole discussion has nothing left with the initial 
topic: is it not so much to migrate source:maxspeed into maxspeed:type 
since source:maxspeed is not the source as in the osm sense but the type 
of panel (or its absence) having effect on the way concerned.
if it is already so difficult to make progress on this point, I find it 
difficult to imagine that an even more important change could lead to 
something other than an additional new scheme and therefore an even 
greater fragmentation is even more duplicated information
