|There's more than one way to do things|
It's a labor of love and you've enjoyed it. Why should a new platform/integration take that away from you?
Sure, the new platform may peel off a few users. Alternatively, it may also help enable new solutions/opportunities.
In the spirit of TIMTOWTDI, you do what you enjoy and let everything else take care of itself.
(If it stops being "fun," that's when you think about doing something else. Until then, you be you...)
That's my take. YMMV.--f
(Update) P.S. Re-reading, I think I may have misunderstood your original question, which seems to be more about whether it's worthwhile to integrate with the new stuff, rather than to compete with it. My answer is the same...and for pretty much the same reasoning, only adding that your earlier work may help those without that background come up to speed more quickly, thereby showing that Perl (still) has active, knowledgeable, and helpful members of the community. (Which isn't to say that the opposite is true.)
