ProductUnitPrecision and ProductUnit are not extendable entities which makes not possible to extend it in "oro way"

[yaroslavbr]

Are there any reason why ProductUnitPrecision and ProductUnit are not extendable entities

orocommerce/src/Oro/Bundle/ProductBundle/Entity/ProductUnitPrecision.php

Line 23 in 707887e

class ProductUnitPrecision implements ProductUnitHolderInterface

?

This limitation makes not possible to simply extend these entities with new fields with common oro approach. As for me this is very common case when you need to add additional rows to these fields (eg. add quantity limitation, some additional data etc).

Recently came across a practical case where I needed to add extra fields on those units ;D
