My parents live on land…

My parents live on land zoned as agricultural, currently making it impossible for them to sever a parcel of it for me to build a house on. When I herd the news there was proposal of a bill that would allow this my parents and I were very excited that we would finally be allowed a severance, allowing my family and I to move closer to them, and be close by to help them as they age and require more help.
While I understand the concerns of some farmers being concerned about the loss of agricultural land , there are also many farming families in my position that are just trying to move closer to their aging parents which would allow this ageing population the ability to stay in their farming homes for much longer with the help of their children.
With that my thoughts on this proposed bill is, would it perhaps be possible to amend the current proposal of three lots per agricultural parcel to one lot per agricultural parcel with the intended use being for family of the current owners.
