I guarantee that people substituting "good" for "well" doesn't come because of French Immersion. Your kids will easily pick up English from you, their friends, their hours of English classes, television, etc. The only disadvantage I've ever heard is unfamiliarity with certain terms in math, but I think that's a bit weak since a grasp of mathematics transcends any language.
One of the other tremendous benefits of a good French Immersion program is that they do things like sentence analysis which can be tremendously beneficial to understanding both English and French. They never cover things like syntax and sentence analysis in English classes.
I have to agree with that about math. I've known quite a few exchange students in my math classes, esp. from France, Germany, Switzerland, etc. who did just fine in fairly advanced mathematics courses. I think most of their difficulty came in keeping up in informal discussions of ideas among peers. I think reading academic papers in a second language might be tough, but that's probably because they're sometimes too dense even for someone who is fluent. You often figure out what the author is saying by looking at the math.
I mainly learned the names for verb tenses and parts of speech (etc.) in french (core) class. I refer to them by the french words, which sometimes makes me laugh. The students from FI elementary in my HS french classes had apparently never had any formal grammar lessons in french or english, which shocked me. Most of my exposure to grammar was in french, but we spent at least some time on it in english. Too much time was wasted learning words like hoary, which can't really be used anymore.
