I gather from your comments, haughtney1, that you are unable to actually read a SID chart and apply height restrictions, as appropriate.
One then wonders...how ever have you been able to cope for all these years? Height restrictions on many SID charts have been there seemingly forever.
The original proposal appears to have been poorly thought out and written, however...to suggest that height restrictions be removed from all SIDS (as checkboard mentions) would only add to RT use...and additional confusion.
