I wouldn't have thought it would harm it at all, it's only for a second or two on tickover, nothing like the valve has to cope with under load, the valve already running at high temperature & combustion pressures. When the decompressor is opened the cylinder won't fill properly & fire properly as there is no induction & compression.
