Highway Links usage for unusual 2-way u-turn ramp

Learning more about highway links and looking for clarifications on whether the definition would fit these unusual 2-way u-turn access roads along a primary highway in Thailand.

These were built recently during the upgrade of the main primary highway between Chiang Mai and Chiang Rai. There are a dozen of them along the highway.

Their sole or main purpose is to provide u-turn access in both directions. Lanes are marked with a yellow line separation.

In some cases, some provide access to a farm track, a few properties, or even a side road giving access to a settlement.

Would these u-turn road segment qualify or not for primary_link, and why?
