Julien, Speaking for Hans? Probably not a great idea...
But, I think he is reflecting the fact that it would be you writing it, so you will have to embrace its worth-while-ness. It is much trickier to guess if the work is going to be valuable for Dia users as a whole. So many users never engage with the developers, there is no marketing function, no one going out an quizzing the populace for their wants and desires. I know there is all sorts of capability I have never investigated, I just make Dia-grams. I actually do like the idea, but I use SnagIt to get a similar effect. (Paid for software :-( ) If you get it working well, it doesn't effect the long term development plans, and you have engaged with them to smooth the integration, it will probably get integrated (the "probably" I have no control over so it is worth little). But you can see, if it is worthwhile to you, then go for it.
