Fwiw, here we do _essentially_ - & partly re profiling builds:
---
$ mkdir -p "${TOPLEV_WORKAREA}/${PKG_LBL}/{src,cfg,bld,inst}"
.
.
$ rm -rf "${TOPLEV_WORKAREA}/${PKG_LBL}/" # With sanity checks. (!)
---
That gives more-or-less as much flexibility as wanted/needed; incl that
it doesn't require essentially pointless wranglings over whether some
package really does now or will in the future, require separate dirs for
cfg/build/&c.
As for assisting users: maybe it is now time to put such commands into each
(relevant pkg-compile) page explicitly; use xml/&c template inclusion,
overridden in non-default cases - usual stuff.
