Should all portions of a package be optionally installable?

In other words, should IPS support options to omit files
from installation by regular expression?

You seem to want to treat packages of software as a development
kit, to be edited and changed as desired.  This is a fine idea, but
rather different than the publisher had in mind.

The function of a packaging system is to deliver the software as 
specified in the packaging manifest.  The file ownership, permissions,
dependencies, etc specified in a package are part of the design of that
software system.  Allowing "edits" by admins means that package can
no longer satisfy any external dependencies, and may well not be 
functional by itself.

No.  If you want to do this, we should publish the docs in separate
packages, and reference them as faceted dependencies.  A single group
package (the equiv. of SUNWman today) could bring them all in.  This is
likely the direction we'll head anyway, since it greatly facilitates
publishing.
