Twisted is a general purpose library&#x2F;framework with lots of features. This is the &quot;huge&quot; part. In my previous projects I have used it a lot and appreciated it.<p>What I was trying to tell is if Scrapy uses only small part of library, it may be possible for developers to use similar constructs from Python&#x27;s standard library. In any case dependency is dependency and it is always better to minimize code footprint.
