About these statements, let us start our discussion by analyzing them:

In both we found the verbs stand out and proliferate accompanied by the pronoun if, a fact that leads us to the notion that they, according to grammatical postulates, present themselves as pronominals, that is, those verbs that require the use of such a pronoun with them. However, it is up to us, language users, to verify, to certify if this linguistic occurrence really takes place or not.
Well, in response to this question raised, it is worth stating that in the case of predication, both the verb to excel and the verb to proliferate are conceived as intransitives, thus dispensing with the use of the oblique pronoun (if). In this sense, returning to the first notion - demarcated by the fact that they, supposedly, are conceived as pronominals, it is noteworthy that they are not. Therefore, let's rectify the linguistic utterances that served as an example:
Do not stop now... There's more after the advertising ;)
