Introducing re-meshing leads to additional synchronisation points and re-paritioning work.

To reduce this cost as much as possible, I suggest requiring adaptive meshes be tagged as such.

<mesh name="Mesh">
  ...
</mesh>

<participant name="Sender">
  <use-mesh name="Mesh" provide="true" adaptive="true" />
</participant>

<participant name="Receiver">
  <use-mesh name="Mesh" from="Sender" />
</participant>

This allows us to:

• disable all re-meshing features by default.
  Existing configurations will work out-of-the-box without any performance impact.
• enforce that only Sender may use resetMesh(meshID) to reset and redefine the mesh.
  This restricts which meshes need repartitioning on which participants.
• enable the intra-participant handshake only for Sender, as it provides an adaptive mesh.
  The Receiver does not need this handshake and can skip it as it will never be able to call resetMesh itself.
• enable re-initialization only between Sender and Receiver (everyone using Mesh from Sender)
  Other participants will never re-initialize as they don't come in contact with participants providing adaptive meshes.
