Comment (by fredj):

 Replying to [comment:2 tschaub]:
 > Hmm, that's anoying.  The idea with point, path, poly handlers is that
 they were "sketch" handlers - they wrapped up what happened when creating
 new features.  It does sort of make sense to give the modify feature
 control a sketch handler or something similar.  We'll still run in to
 issues if we start getting fancy with layer events (like I think we
 should).  Say someone is listening for "featureerased" on a vector layer.
 Then when modification starts, if we use a temp sketch layer (controlled
 by a sketch handler or something), then we'd want to erase the feature on
 the real layer and draw it on the temp layer.  Whomever is listening might
 get confused by that "featureerased" event.  So, we'll want to add a
 "silent" or "noEvent" option to things like eraseFeatures.  All that makes
 me think we should add the same sort of option to addFeatures.

 Does the modified geometry really needs to be removed from the original
 layer ?
 If we only copy it to the tmp layer, the original geometry will be visible
 in the background and it could improve the tool usability.

 But I certainly miss other issues that ca be resolved by your proposal.

 A other possibility is to copy the maps.google modify feature behavior:
 create a tmp layer to display a linestring representing the current
 modification.
