You seem to be ignoring comments from other people (Lars Hellström and
Harald Hanche-Olsen) who have some other experience.

I'm not arguing against this statement: the design of all glyphs,
including the Aring glyph, is dependent only on the style of the whole
font and its aspects.

We are discussing the case when there is NO Aring glyph in the LaTeX
font encoding, such as OT1 or T2A font encoding.

In this case, we HAVE TO construct the Aring glyph "artificially", and
we have two ways of doing that: either just apply the ring to A using
an \accent command, or put the ring closer to A using the approach
currently used in ot1enc.def.

There are valid arguments to do the latter, as Lars Hellström and
Harald Hanche-Olsen pointed out.

May it be the result of incorrect metric for A and/or ring glyphs?

Do you have a complete list of "other fonts"? Wouldn't it look ugly if
we were dependant on font families in the generic encoding definition

I see no way to do that properly.

Remember, we are discussing the case when the font encoding does not
contain the pre-built Aring glyph (in case it does contain that glyph,
it's appearance is in the hands of font designer).
