Does the Esoteric Magus ability Ki Arcana count as "gaining a ki pool as a class feature"?

[Renlar]

I would like to know if the Esoteric Magus ability Ki Arcana counts as "gaining a ki pool as a class feature" in order to determine if I can take Monk Vows with a 1 level dip.

Yes, it's a class feature.

Also, "any user of ki" can take vows, so you're good either way.
