I think some of the shortcomings you point out, such as listening history sync and export to other apps, are caused by lack of financial incentives. Sync is a feature a lot of users would pay for (see Pocket Casts and PlayerFM). Export listening hisotry would just allow for other apps to take over their user base, though I think Podcasts Addicts has such a feature for backup/restore purposes. As for reviews, podcasts are so decentralized that I'm not sure where one would start with aggregating reviews. And smaller apps probably don't want to deal with the trouble of moderating ratings and reviews on their own platform.
