My understanding of the spirit of the rules behind trading halts is that they are there to minimise insider trading opportunities, i.e. to allow a company time to get information out ahead of the rumour mill before trading begins.
While some companies might use a TH unnecessarily to gee up expectation about an announcement, it is not good form generally because you are restricting people's right to trade. There can be enormous opportunity costs in some instances.
The other consideration is that not all THs precede good news. They can precede disastrous news as well. So be careful what you wish for.
Just my thoughts.
