Qrow and Raven are NOT 30 or younger. It's exactly like Sentry said. Lionheart said the Spring Maiden ran away over a decade ago (Over 10 years ago). Raven was under 30 when she received the powers, but that does not mean she cannot keep the powers.

There's absolutely no way for Qrow and Raven to be less than 30 years old unless Raven had Yang when she was '12 or 13 years old at most. TWELVE or THIRTEEN years old.' Yang was 17 in Volumes 1-3, and 30 minus 17 is 13. Yang may be 18 as of Volume 4 or 5, and 30 minus 18 is 12.

Huntsmen graduate the academy at about age 21. They start at age 17 (unless they're like Ruby, but she is likely a rare case), and Ozpin said they would be attending for 4 years. 17 plus 4 is 21. Raven stated that she and Qrow were "the right age" to start attending Beacon, so they were most likely 17 when they began their first year, meaning they were 21 when they graduated. And they did graduate, considering Qrow blatantly stated that STRQ graduated in Volume 3. It is highly unlikely that Raven gave birth to Yang while they were attending Beacon because she left soon afterward, and like I just said, STRQ graduated.

So the youngest that Raven gave birth to Yang was most likely 21... and that was about 17 or 18 years ago. 21 plus 17 is 38, and 21 plus 18 is 39. So, once again, it is quite literally impossible for Raven and Qrow to be 30 or younger.

Though, you are right that it wouldn't be pedophilia, considering Winter is in her early 20s and thus not a teenager or a child. Some people just don't feel comfortable with shipping someone in their early 20s with someone who is on the verge of being 40 or is possibly older than 40.
