Does the 2e large dragonkin have 10' reach?

[Bics]

Size of the ancients, level 17 dragonkin ancestry feat. It makes you huge for a minute and it says you add 5' to your reach and if you are a shipborn dragonkin you add 10' to your reach. That implies a large dragonkin starts with 10' reach at first level which it does not say on the statblock.

[Gamerskum]

Creatures only have reach if they say it in their stat block and from the additional resources page for Galaxy guide...

Remove the linguistic trait from the Telepredict feat (contemplative ancestry feat, page 140).
Large PCs do not have an increased reach natively, though some feats may increase their reach.

[Squark]

The line about shipborn dragonkin appears to be borne of confusing 1e and 2e mechanics. All Dragonkin start with a 5 foot reach.
