I wouldn't think so... 24-bit PCM already has 144dB of range, and few, if any ADCs take full advantage of that.
Background noise in most quiet rooms is above 20dB, even, and likely much louder in venues with ventilation and other people breathing.
32-bit float is convenient for post-processing, since most software uses 32-bit float internally and will convert wav/flac/whatever to float for calculations before reconverting it back to wav/flac/whatever.
I wouldn't rely on float as a storage/archival format, though, since it lacks metadata and built-in checksumming.
Larger sizes also means more wear on storage devices and higher likelyhood of bitflips and data corruption.
My recorders only support 24-bit PCM wav (and nominally so, ISTR the M10 only has about 80-something dB of dynamic range).
I always FLAC everything ASAP to multiple HDDs (using btrfs on Linux) and do all post-processing on machines with ECC memory to avoid bitflips.
