Commentary

The vowel of a अङ्ग (stem) ending in a consonant does not get वृद्धि when the स् (सिच्) takes the augment इट् ।
As अदेवीत्, असेवीत्, अकोषीत्, अमोषीत्, but अलावीत् where the root ends in a vowel. Will not लू by taking Guna (which is an antaranga operation) and the substitution of अव्, become a root ending in a consonant? No, though Guna is antaranga, it is superseded by the express Vriddhi.
