System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1080 with Max-Q Design/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.96

Blender Version
Broken: version: 3.3.0 Alpha, branch: master, commit date: 2022-05-25 21:21, hash: dc6fe73e70

Short description of error
The edit mode vertex_weight_paste operation is supposed to copy the weight of the active vertex group from the active vertex to all selected vertices. However it does not copy to unassigned vertices.

This behavior is confusing since some selected vertices will receive the value and some not.

Exact steps for others to reproduce the error
Copy VGroup.blend

Click on the vertex_weight_paste icon

Only the vertices that where previously assigned get the active vert's weight value

On the other hand the vertex_weight_copy operator, which is meant to copy all weights from all vertex groups in the active vertex to all selected vertices, does copy even to unassigned vertices giving the expected result.

Can confirm, will check if there is a hidden reason for this

Yeah, assume this should be made consistent.
