For image resizing, I am one of those who disagree.

That's OK. To be honest, I can hardly see a difference between my resampling algorithms applied in RGB or CIE L*a*b*, in continuous-tone images. Thus, my preference is more based on theoretical observations. There is, of course, more of a difference when applied to non-continuous-tone images.

So, from a pragmatic point of view, you may want to argue that the theoretical difference is hardly worth the convertion effort (assuming source color space and desired destination color space is RGB). Myself, I provide different quality levels in my imaging stuff in order to not have to make the hard choice between being fast and being correct. First two quality levels agree with you, in the above mentioned situation, third and highest level dissagrees. I hope you're not contradicting the theoretical observations, though, then I would have to dissagree.

And of course, this topic has nothing to do with TIFF.

Sure, but most of us might be interested anyway. TIFF is not a database file format, is it? This is all closely related to our field of interest, at the very least.
