There seem to be some here who cite obscure cases with no clear references, making sure to use untranslated Latin to make themselves seem clever, which essentially make the cult favouring claim that essentially reads the mind of bishops some trads don't like, and finds their intention wanting. It comes from the same stable as those who invented non una cuм, a horrifying error refuted by looking at an older missal where after the Pope and bishop, the monarch (who was often or always non Catholic, barring one or two deathbed conversions like Charles II). Obviously the ultimate point is that any one who goes to a chapel other than that of the cult leader or similar, goes to hell. The Plinioites who hate Archbishop Lefebvre do the same thing even though they usually go, at best, to diocesan TLM masses, like Attila Sinke Guimares who has such delusions that +Lefebvre had a personal masonic brass band, that +Lienart was obviously a freemason, and other delusions which suggest there is something in the water in Brazil. Who is +Lefebvre compared to holy Plinio de Correa?

By making that declaration, you're not doing what the Church does.  You're thereby taking it out of the context of an ecclesiastical act.  With +Lienart, we're talking about a situation where he showed up at a Catholic cathedral and conducted the ordination ceremony that by all appearances was an official function of the Church.  By declaring outwardly "I have no intention to baptize." you're actually adulterating the form of Baptism ex adjuintis.  You perform it in a CONTEXT which makes it quite clear that you don't intend to do it.  Just as if a couple people were goofing around pretending to be baptizing each other; the context there indicates that they are not intending to perform the rite but to merely simulate it.

If some diary entry of +Lienart came out tomorrow stating, "When ordaining Lefebvre, I deliberately withheld my intention." I would still not hesitate for one second to go receive the Sacraments from an SSPX priest that was ordained directly or indirectly by +Lefebvre.
