Very important development if it happens. Egypt has thus far kept their borders closed, and as all the land borders with Israel are closed, Palestinians really have nowhere safe to go to avoid Israeli bombs. The IDF has not been really subtle in their public messaging that they are expecting and tolerating lots of civilian casualties.

The one, possibly two, carrier groups going to the Eastern Med are clearly meant to try and dissuade other regional actors from getting involved.

I agree it's important that Palestinians have a safe corridor to exit.  
I agree with your assessment that safe passage for civilians benefits all parties.  
I agree that Israel's public messaging has disclosed a lack of intention to surgically tailor military action to avoid civilian casualties.  

An additional fact that seems important is the death toll on the Palestinian side.  
As of now, there are 1,900 reported deaths in Gaza, including Hamas members.
Unless that number is well below reality due to a delay in counting casualties, that number seems remarkably low for the number of air strikes.
To me that suggests that, to date, Israel has been more careful about civilian casualties than its leaders are professing.   

I have a few interpretations of the events that may differ from yours:
(1) I think Israel would like to avoid civilian casualties to the extent that is possible, consistent with its legitimate military objectives.
(2) I don't think Israel has any desire or intention to engage in ethnic cleansing.  
(3) Prudent or not, I think Israel may be trying to scare civilians into leaving so that fewer civilians die.  
(4) I think Israel is relieved that other countries, especially Egypt, are helping to provide a civilian corridor.
(5) I think Israel was disappointed, but not surprised, that Hamas urged Palestinian citizens not to flee so that they could be human shields, which is a violation of the laws of war.
(6) Based on these points, U.S. messaging that Israel should delay its ground invasion to allow civilians to flee may not be upsetting to Israel.
