I am in Califnornia. There are so many strong motion seismometers installed around here, almost building-wise. But as far as I can recall, I do not remember I have ever heard from the news that intensity was announced to the public. I had also experienced Hiacheng and Tangshan earthqukes, I never remember intensity had been mentioned to the public. Strong motion seismology is not my field, I should not say much about it. However, to my point of view, intensity is more useful as a reference for earthquake engineering. Even in that case, g is much more useful, because all earthquake designs depend on g, and all seismic risk probablility maps are in g. During an earthquake, everybody is frightened and in panic, so to my point of view, technical announcement should be kept as simple as possible to avoid unnecessary confusion and the risk of unnecessary public panic. I believe that is why they do not announce intensity here and in China.
