I’d argue those still count as messing with the consonants, given they’re usually from [Vn, Vm]→[Vŋ]→[Ṽ] in Portuguese, French, and Lombard. And old Romanian, too (the language eventually lost them, but apparently it had nasal vowels at some point).
In fact some in Portuguese still interpret those nasal vowels as vowel+consonant sequences, proposing some “nasal archiphoneme” for that. e.g. “lã” wool /laN/. Often due to the presence of a nasal appendix (trailing nasalisation, after the vowel ended) in those words. I personally don’t buy it, but hey, still consonant weirdness!
Plus weird nasal vowels in Portuguese and French

Now that you point it out… Sim.
