While the plaque is due to his 1931 visit, I think the plaque itself is quite recent, and has been a point of controversy from the start. The same applies to the one honouring the Shah of Iran, but there the objections come from Muslims, who object to people walking over the name of the Prophet.

Incidentally, France renamed the last street named after Pétain a few years. The same des not apply to Petain (sic) Ave in Milltown NJ.
