"Changing the rendering" is something we can each do for ourselves.
What we can't do is tell anybody else to change their rendering.

Yes.  We've seen this done on topOSM for a year or so and on MapQuest
more recently.

Have you got a demo of what you are suggesting?  It sounds like you
are suggesting rendering the shield beside the reference number.
Would the shield have number in it as well, then the larger, more
legible number beside it?

Here are a couple of examples from my shield server.

1) Tampa, FL


Interstate and US route shields.  Normal and wide.

2) Los Angeles, CA


California state route shields, normal and wide. In contrast to the
Interstate shields, I left the "California" text in place and reduced
the reference number size.

3) Syracuse NY


US route shields normal and wide.

4) Guelph, Ontario


Highway 6 meets highway 401 and is coincident for one exit.  401
continues West-East.  Highway 6 continues North from the West and
South from the East.  Notice a couple of things in this example.

a) clustered shields.  I don't know how to do this yet without a hack.
 Ideally, I'd like this to be something clever that detects
overlapping route relations, and assembles clustered shields from
their individual shield images.

b) two different shield styles for 6.  The old style is a 1:1
pixel-built png shield with a larger numeral. The newer style is
reduced from a larger svg.
