Making 50 ft a priority when there is no obstacle to overfly is unnecessary I agree. I don't understand the objection though to using a 'best angle' climb (VX). All pilots should have been properly trained to do this safely and at many airfields due to obstacles it is the standard practice.
All that you need to know; runway dimensions and TODA etc is known before you leave the club house plus, of course, the aircraft capability. All this stuff is made available to ensure the take off is predictable and possible without exceptional skill. The best advice, in my view, is never turn back from the climb out following an engine failure.
... is a safety compromise in EFATO to get you over an obstacle.
The 'best angle' climb (VX) gets you to height in the shortest distance. The 'Best rate' climb (VY) gets you to the height in the shortest time. The VY climb provides the better options in the event of a EFATO in my view.
