All I can say is that since using AADC, editing PDFs has become a real pleasure.
instead of fixing the source? (i'd probably opt for html then)

I have no source; I have a PDF, originated by a third party, which I need to amend (e.g., to illustrate what can be achieved or what is desired).  I have done this with wine lists, advertisements, posters, etc., sent them back to the originator, and he or she has then been able to incorporate the requested amendments in the original (Photoshop / InDesign / Illustrator / etc.) source.

but ... given this thread: we're talking of archiving and editing a scientific archived article is imo "not done'

Why is it about *just* that?
It is about adjusting pdfTeX to be able to produce PDFs that are useable in a variety of modern contexts. Editability is one of those aspects. 

As a lecturer and academic, I use (La)TeX for a wide variety of document types.
Why should I need to use completely different software applications for class materials, lecture notes, student tests, examinations, performance reports, grant applications, conference reports, special demonstrations, and much more?

The answer is that I do not have to with TeX, provided it allows to do all the special things in a reasonably consistent way, and all can exist compatibly within a PDF file.
A feature that is obviously useful in one context could be useful also for other types of document.


Fine, that is a very different matter.

No, it is not.
Everything that Philip has said that he does with PDFs is very appropriate for this discussion.
Essentially we need to keep TeX relevant to document production in the current age, and into the future.


and ... for texies, if then make a pdf, they do have a source, so they can fix the source and regenerate the pdf (which also keeps them in sync)

Even when working collaboratively, you do not always have the full source.
I frequently use APro to add hyperlinks and logos into otherwise sterile-looking PDFs produced with TeX by others, before making the resulting PDF available, linked from public pages of a website.


Agreed.
