If this were a plea, it would certainly make the entry into Jerusalem a revolutionary challenge to the powers that be? See the line quoted in Wikipedia from [iH]esus Christ Superstar[/i] (Ibid)
Could this have been the final straw for the Sanhedrim?
They took palm branches and went out to meet him, shouting, “Hosanna!” “Blessed is he who comes in the name of the Lord!” “Blessed is the king of Israel!”

The word hosanna (Latin osanna, Greek ὡσαννά, hōsanná) is from Hebrew הוֹשִׁיעָה־נָּא, הוֹשִׁיעָה נָּא hôšîʿâ-nā, and especially the short form הוֹשַׁע נָּא hôšâ-nā, and related to Aramaic ܐܘܿܫܲܥܢܵܐ (ʾōshaʿnā) meaning 'save, rescue, savior'.[2]
In the Hebrew Bible it is used only in verses such as "help" or "save, I pray" (Psalms 118:25). However, in the Gospels it is used as a shout of jubilation,[3] and this has given rise to complex discussions.[4] In that context, the word Hosanna seems to be a "special kind of respect" given to the one who saves, saved, will save, or is saving now. If so Hosanna means "a special honor to the one who saves." The literal interpretation "Save, now!",[5] based on Psalm 118:25, does not fully explain the occurrence of the word.[3]

Is it the crowd's hope/plea that Jesus would be restoring the kingdom to Israel?
Is there any indication in the story that Jesus's kingdom is not like an earthly kingdom
