Issue: Date Picker should use default XF date picker.

This is fixed in the next release in XenForo. The one place that uses a date picker now uses the XenForo date picker.

Still need to switch this to the vBulletin date pickers.

Is it worthwhile investign in vbulletin development before vbulletin comes out with a version that people actually want to use? Sooner or later vb3 and 4 will be EOL. Either by vbulletin itself or by Google, technology deprecation or irrecoverable security exploits. If no vb5 is still not fit for purpose in a year or so, there will be few sites on vbulletin left.

Regardless of that, vBulletin 3 and 4 together maintain about 35% marketshare, and vBulletin is still similarly represented among our users. We will continue to develop for and support users on any of the minimum software requirements that we supported at 4.0.0 Alpha 1 until such time as they are EOL, we have at least a secondary point release to drop support, and there is market research to support dropping support at that time. We will not do so beforehand unless there is significant reason to do so, such as an active infection among those versions. We still have to support users who use PHP 5.3, even though PHP 5.4 and 5.5 are already EOL.

The built-in vBulletin date picker can now be used for this field as well.
