My humble thoughts:
Like any good work of art it is hard to know when enough is enough
and it's time to leave the piece as it is. I am worried that what
was once a clean and elegant spec will become muddied to support
features that, imo, tools should have taken the burden; take required
bundles for example.
I'm not aware of the compelling use cases that call for an extension
to the number of hosts for a fragment but can think of one, again
imo, not so compelling one. This being the patching of a set of
bundles with one fragment. I'm happy to go into detail as to why I
think poorly of this use case if it is the impetus for adding this
extension and if this is the appropriate forum.
About PackageAdmin.getHosts(), I assume that for the moment it should
always return a single host. Just curious, was there a reason to
have it still return an array and not a scalar in light of the
current cardinality between host and fragment?
Is there a way for me to know what's in the pipeline so that I may
put in my 2 cents?
Regards,
Alan

During R4 spec development we allowed fragments to attach to multiple
hosts. Prior to going final on R4, we changed course and limited
fragments
to only attach to a single host. The sentence you quote is left
over from
when we considered allowing fragments to attach to multiple hosts.
Also
see the method signature of PackageAdmin.getHosts where the return
type is
an array and not a scalar.
We are currently discussing revisiting that decision. That is, to
potentially allow a fragment to attach to multiple hosts. It would be
useful to get input from the OSGi community on the pros and cons of
such a
change.

[osgi-dev] Finding Localization Entries
Hello,
I'm trying to get my head around 3.10.1 Finding Localization
Entries. The last sentence of the first paragraph confuses me.
"Fragment bundles must delegate the search for a localization entry
to their host bundle with the lowest bundle ID."
Does this mean that fragment bundles can have multiple hosts?
Regards,
Alan
