Parent Pom: Needs some "do as I say, not as I do"
I think there needs to be some additional POM elements that allows a
parent POM to provide defaults to a child POM that are different from
the values used by the parent POM itself.
Here's an example:
In my parent POM, I want to say
<url>http://tapestry.apache.org/tapestry5/</url>
But I want all my child modules to use the URL:
<url>http://tapestry.apache.org/tapestry5/${pom.artifactId}</url>
I could see this expressed, in my parent pom, as something like:
<project> ...
<url>http://tapestry.apache.org/tapestry5/</url>
...
<childDefaults>
<url>http://tapestry.apache.org/tapestry5/${pom.artifactId}</url>
</childDefaults>
...

There's logic behind that.. project URL and scm URL's are indeed
modified in the children, but that's necessary. If they didn't you'd get
collisions, i.e. 2 module's sites overwriting each others html files,
or 2 modules sources being overwritten in a repository.
I think these are sensible defaults that can be overridden. But the urls
mentioned above MUST be different for modules, so just inheriting by
default will produce problems. Everything that doesn't have to be
different is 'straightly inherited'.

AFAIU it currently depends on the semantics of the tag whether
there is straight inheritance or not ...which is IMO not very consistent

I think this would be a worthwhile addition to JIRA. I'm not sure if
it's already in there. I know it was pointed out as an issue a while
ago and we were going to look at changing the behaviour from automatic
append to controlled appending by expressions like you've highlighted
in a future version of the POM.
Would you mind filing it?

On some things that happens automatically. The child's additional path
element gets added to the default from the parent.
I do not remember which do it and which dont. One that seems to do it is the
scm url. Another is the deployment url.
