I've seen this or something very similar before in an old book on ATM. Whilst the diffraction spikes appear smaller or even appear gone the energy is simply spread out over a wider area impacting on contrast.
Whether a loss of contrast bothers you depends on what you're looking at as does the appearance or not of a bright spike. The only way to eliminate the diffraction caused by the spider vanes is to not have any whether they be straight, curved or otherwise masked and that's not possible with a standard Newtonian design.
